The optimum drilling technique in the northeast area of Sichuan

Han Laiju,Ma Guangjun,Zhao Jinhai

Strategic Study of CAE 2010, Volume 12, Issue 10,   Pages 44-49

Abstract:

Geological conditions in northeast area of Sichuan are complicated, such as poor drillability in terrestrial formation, severe deviation in high angle structural belt. Pressure system and strata lithology in this area is also complicated, which causes many complex cases and accidents like lost circulation and collapse when drilling. Besides these, this area have "high pressure, high production, high sourness"  features. ROP was slow and drilling cycle was long. In order to increase ROP of complicated deepwell in south China, through introducing and developing new technology and new tools, like gas drilling and vertical drilling equipments, combined with existing techniques such as underbalanced drilling, compound drilling, optimum drilling technique system fit for complicated deepwell in northeast area of Sichuan was formed, which improved ROP and wellbore quality of complicated deepwell in south China.

Simulation of flow excursion and thermal siphon under natural circulation condition with lower pressureand lower quality

WANG Jianjun, YANG Xingtuan, JIANG Shengyao

Frontiers in Energy 2008, Volume 2, Issue 2,   Pages 169-173 doi: 10.1007/s11708-008-0044-z

Abstract: The simulation of flow excursion was conducted under HRTL-5 condition. The mechanism analysis and the simulation of thermal siphon process were also performed. The result shows that the computer code can be used to simulate the static instability of a natural circulation system and the simulation of flow excursion almost conforms to the experiment result.

Sensor-guided gait-synchronization lower-extremity-exoskeleton for potential application on unilateral Research Articles

Donghai WANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 920-936 doi: 10.1631/FITEE.2000465

Abstract:

This paper presents a gait-synchronization system to help potential unilateral knee-injured people walk normally with a ed (LEE). This relieves the body weight loading on the knee-injured leg and synchronizes its motion with that of the healthy leg during the swing phase of walking. The gait-synchronization system is integrated with a designed to sense the motion/gait of the healthy leg. Guided by the measured joint-angle trajectories, the motorized hip joint lifts the links during walking and synchronizes the knee-injured gait with the healthy gait by a half-cycle delay. The effectiveness of the LEE is illustrated experimentally. We compare the measured joint-angle trajectories between the healthy and knee-injured legs, the simulated knee forces, and the human-exoskeleton interaction forces. The results indicate that the motorized hip-controlled LEE can synchronize the motion/gait of the combined body-ed LEE and injured leg with that of the healthy leg.
